<h3>TMPNAM(3)           Linux Programmer's Manual           TMPNAM(3)
</h3>

<h3>NAME
</h3>       tmpnam - create a name for a temporary file

<h3>SYNOPSIS
</h3>       #include &lt;stdio.h&gt;

       char *tmpnam(char *s);

<h3>DESCRIPTION
</h3>       The  tmpnam()  function generates a unique temporary file-
       name using the path prefix P_tmpdir defined in  &lt;stdio.h&gt;.
       If the argument s is NULL, tmpnam() returns the address of
       an internal static area which holds the filename, which is
       overwritten  by subsequent calls to tmpnam().  If s is not
       NULL, the filename is returned in s.

<h3>RETURN VALUE
</h3>       The tmpnam() function returns a pointer to the unique tem-
       porary filename, or NULL if a unique name cannot be gener-
       ated.

<h3>ERRORS
</h3>       EEXIST Unable to generate a unique filename.

<h3>CONFORMING TO
</h3>       SVID 3, POSIX, BSD 4.3, ISO 9899
